Examples
Example 1: ORIC
If ORIC is active and there are two or more blocks with changes in orientation (e.g.A2=...
B2=... C2=...) programmed between traversing blocks N10 andN20, then the inserted
circle block is distributed among these intermediate blocks according to the absolute changes
in angle.

Comments
; The circle block inserted at the external corner is
distributed between N12 and N14, corresponding to
the change in orientation. The circular motion and
the orientation change are executed in parallel.
